  • the process of manufacturing the second item (shock-absorbing air- cushioned sheet) which was the modified version of the first invention is as follows ; First, place several air tubes on the flat sheet and fuse one end of the tubes to the sheet.

We, however, face some problems here, too.
  • the air-filled bumps are formed using only one air tube unit, giving less cushioning than expected. Another unnerving matter is that it is impossible to pump the air into the tubes when it is needed.

Similar to the above item, this invention has no device for pumping the air or adjusting the air pressure. After all, the problem is that the air layer seated inside the bumper cannot effectively buffer the shock in case of a vehicle's hitting a pedestrian or in minor cases.
  • This invention is the modified form of previously-filed items, designed to solve their problems.
  • the major characteristics of the invention are as follows; To begin with, the base sheet has bumps within which air tubes of different air pressure and size along with elastic material are seated.

As it is widely acknowledged, in car accidents many of serious injuries afflicting a driver or passengers are caused by the crushed hard plastic- or steel-made car parts. If a car's inner side of a roof or headrests, most of which are made of textiles or urethane foam, are produced using the above-related invention, the possibility of those injuries can be significantly reduced. Similarly if the invention is mounted on a vehicle, it saves the cost taken to replace a broken or crushed bumper with new one. Besides the manufacturing process is very easy and simple so that it is possible to reduces the manufacturing cost as well as the weight of the finished buffer.
  • the tubes can be effectively replaced by elastic material(19). Furthermore, given the increasing concern of environmental pollution, currently-used sponge and urethane which are not recyclable should be replaced in the long run. And bumpers need to be designed to reduce the impact on pedestrians hit by cars.
  • the air-cushioned buffer may well be employed in manufacturing the safety-oriented vehicles in the future. Because it effectively absorbs much of collision-shock by allowing the air bags in the space 2(7) to instantly inflate. These air bags in the space 2 (7) can be acted by the voice-detecting sensor as well, effectively decreasing casualties.
  • the invention can be adopted into any parts vulnerable to the impact of a vehicle. It may be seated inside a car to prevent drivers' knee injury. Adopted to the sides, the double-layer pressurized air plays as impact bars to ideally buffer the impact.
